56 | ;; GENERAL OVERVIEW | |
57 | ;; | |
58 | ;; This package installs numerous hooks to colorfully highlight your | |
a1506d29 | 59 | ;; source code buffers as well as mail and news buffers. Most |
9a5e9959 RS |
60 | ;; programming languages have predefined highlighting patterns. |
61 | ;; Just load hilit19 and files will be automatically highlighted as | |
62 | ;; they're loaded. | |
63 | ;; | |
64 | ;; Rehighlight a buffer by typing C-S-l (control-shift-lowercase-L). | |
65 | ;; | |
66 | ;; If, when you edit the buffer, the coloring gets messed up, just | |
67 | ;; redraw and the coloring will be adjusted. If automatic highlighting | |
68 | ;; in the current buffer has been turned off, then typing C-u C-S-l will | |
69 | ;; force a rehighlight of the entire buffer. | |
70 | ;; | |
71 | ;; Hilit19 can build faces by examining the names that you give to them | |
72 | ;; For example, green/black-bold-italic-underline would be created as | |
a1506d29 | 73 | ;; a face with a green foreground, and a black background, using a |
9a5e9959 RS |
74 | ;; bold-italic font...with underlining for good measure. |
75 | ;; | |
76 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
77 | ;; | |
78 | ;; SETUP -- In your .emacs: | |
79 | ;; | |
a1506d29 | 80 | ;; |
280a6a9f RS |
81 | ;; (cond (window-system |
82 | ;; (setq hilit-mode-enable-list '(not text-mode) | |
83 | ;; hilit-background-mode 'light | |
84 | ;; hilit-inhibit-hooks nil | |
85 | ;; hilit-inhibit-rebinding nil) | |
a1506d29 | 86 | ;; |
280a6a9f RS |
87 | ;; (require 'hilit19) |
88 | ;; )) | |
a1506d29 | 89 | ;; |
280a6a9f RS |
90 | ;; If you like font-lock-mode and want to use both packages, then you can |
91 | ;; disable hilit for the modes in which you want to use font-lock by listing | |
92 | ;; said modes in hilit-mode-enable-list. | |
a1506d29 | 93 | ;; |
9a5e9959 RS |
94 | ;; (hilit-translate type 'RoyalBlue ; enable highlighting in C/C++ |
95 | ;; string nil) ; disable string highlighting | |
96 | ;; | |
97 | ;; To get 100% of the utility of hilit19, you may also have to apply the | |
98 | ;; patches below for info.el and vm5.33L_19/vm-summary.el | |
99 | ;; | |
100 | ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; | |
101 | ;; | |
102 | ;; SETUP -- Are you using the right font for Emacs? | |
103 | ;; | |
104 | ;; Emacs cannot properly find bold and italic fonts unless you specify a | |
733619f9 RS |
105 | ;; verbose X11 font name. If you specify a font for emacs in your |
106 | ;; .Xdefaults, it *MUST* be specified using the long form of the font name. | |
107 | ;; Here's a good font menu: | |
